在pygame中使用midi事件让玩家移动的方法

import pygame

pygame.init()
screen = pygame.display.set_mode((800, 600))

pygame.midi.init()
player = pygame.midi.Output(0)
player.set_instrument(0)
midi_file = "your_midi_file.mid"
midi_events = pygame.midi.midis2events(pygame.midi.MidiFile(midi_file), player.device_id)

player_x = 400
player_y = 300
player_speed = 5

running = True
clock = pygame.time.Clock()

while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    for midi_event in midi_events:
        if midi_event.type == pygame.midi.MIDIIN:
            # 根据midi事件的值来更新玩家位置
            if midi_event.data1 == 64:  # 例如，当按下音符C4时
                player_x += player_speed
            elif midi_event.data1 == 65:  # 例如，当按下音符D4时
                player_x -= player_speed
            elif midi_event.data1 == 66:  # 例如，当按下音符E4时
                player_y += player_speed
            elif midi_event.data1 == 67:  # 例如，当按下音符F4时
                player_y -= player_speed

    screen.fill((0, 0, 0))  # 清空屏幕
    pygame.draw.rect(screen, (255, 255, 255), (player_x, player_y, 50, 50))  # 绘制玩家
    pygame.display.flip()  # 更新屏幕显示

    clock.tick(60)  # 控制游戏帧率

pygame.quit()
